Saponins, tannins and flavonols found in hydroethanolic extract from Periandra dulcis roots

Periandra dulcis Mart ex Benth. Fabaceae (Syn.: P. mediterranea (Vell.) Taub.) is native to the northern and middle parts of Brazil. In Brazilian ethnomedieine, their roots are used as anti inflammatory, expectorant, diuretic and laxative. An HPLC-ESI-MS/MS system was employed to. provide, a rapid method to make a tentative. characterization Of the compounds found in the hydroethanolic extract from P. dulcis roots. The structures of sixteen compounds found in this hydroethanolic extract were suggested Mainly by MS data conjugated with the UV-DAD spectra, reference. compounds and available mass spectra data in literature. Saponin derivatives :of hederagenin and soyasapogenol E, such as hederagenin-3-0-rhamnosyl glucosyl glucuronide, soyasapogenol E-3-0-rhamnosylglucosyl glucuronide and periandrin isomers were found as the main constituents, with-a-minor content of flavonols,quercetin and . myricetin glycosides derivatives and hydrolysable tannins, such as dihexahydroxydiphenoyl galloyl glucoside and trisgalloyl hexahydroxydiphenoyl glucose. To the best of our knowledge, With exception of periandrins found in the roots nothing has been published about the chemical composition of P. dulcis. (C) 2013 Brazilian Society of Pharmacognosy.
